A polymer<span> is a large macromolecule made up of many repeating, smaller units. These units are called </span>monomers, and can vary in size and composition. Polymers can be made from chains of just one type of monomer<span> or several </span>monomers<span>. The number of individual </span>monomers <span>in a </span>polymer chain<span> can range from small to large </span>
